Quick start guide
It is important to carefully select the take-off location, the Start waypoint and the
Home waypoint to ensure your drone remains at a safe distance from obstacles.
The swinglet CAM should always be launched against the wind. Select a take-off
location clear of obstacles (buildings, rocks, power lines, hills, trees, etc.) within
a distance of at least 40 m in the upwind direction. Immediately after takeoff it
will keep its wings level and climb in the general direction it was launched until it
reaches the take-off transition altitude⁶, at which point it will start flying towards
the Start waypoint.
By default, the Start waypoint is set to a distance of 80 m West of the initial posi-
tion of the drone and an altitude of 75 m/ATO. It is good practice to move the Start
waypoint close to and upwind from the take-off location to allow a smooth transi-
tion between take-off and waypoint-directed flight. You can move waypoints by
clicking on them and dragging them within the Map Area⁷.
The Home waypoint is used both as the landing location and as a safety position in
case of an In-flight warning. When initiating a Circular landing around the Home
waypoint the drone will switch off its motor and glide down while circling around
the Home waypoint at the waypoint's radius until it touches the ground.
To prepare a Circular landing, place the Home waypoint in a location that has no
obstacles within a radius of 40 m (or 20 m more than the Home waypoint radius) to
give the drone enough space to land. By default, the radius of the Home waypoint
is 20 m. In high-wind conditions it is recommended to increase this diameter⁸.
Note: In case of strong-wind conditions, the drone may drift even
further than 40 m away from the center of the Home waypoint when
performing a Circular landing. Therefore, it is safer to plan for even
more clearance in the downwind direction.
⁶ By default the take-off transition altitude is set to 20 m. In difficult launch conditions you can set
both the take-off heading and the take-off transition altitude in the Setup Phase tab, as described
in section 'Setup Phase tab' on page 82.

points and how to modify them
